What is 2x - 1 < 7 and 5x + 3 < 3. ? ?

OK 2x + 1 = 5x/3 ; the key here is to get rid of the fraction by multiplying both sides by 3 6x + 3 = 5x ; now subtract 6x from both side 3 = -x -3 = x Proof 2(-3) + 1 = 5(-3)/3 ?? -6 + 1 = -5?? -5 = -5

+1,000)=g7e=mc2-g=7 because if you know algebra you should know g=7 to get your answer

The amount used= 13.04- 1.9 = 11.14
